Qingdao Stone Rubber Products Co., Ltd. Supplier Evaluation

Executive Summary

Qingdao Stone Rubber Products Co., Ltd. is a China-based supplier located in Shandong, with a reported factory area of over 11,000 sqm and more than 50 staff. The company appears to be a medium-scale manufacturer with verified supplier status, 13 years as an Gold Supplier, Trade Assurance support, and platform labels including Finished Product Inspection, Full Customization, ODM service available, and Minor Customization. Its listed products are mainly wheel-related items, including beach wheels, PU beach wheels, PVC balloon beach car wheels, and solid rubber wheels, with MOQs ranging from 2 to 1,000 pieces.

Commercially, the supplier has recorded 20+ orders and CN¥676.1K+ transaction value over the past six months, supported by a 5.0 store rating but only 6 reviews. Delivery performance is strong at 91.7% on-time shipment. This supplier is suitable for buyers seeking verified, medium-scale wheel-product sourcing with customization capability, while review volume and limited service response speed remain key points to monitor.

Detailed Analysis

1. Company Strength

Basis:
- Factory location: Shandong, China
- Factory area: 11,000+ sqm
- Employees: 50+ staff
- Verified supplier: True

Elaboration:
The supplier has a disclosed factory footprint of more than 11,000 sqm, which indicates a meaningful physical production base. The employee count of 50+ staff suggests a small-to-medium operational team rather than a very large-scale manufacturing organization. The presence of verified supplier status strengthens confidence that the company has undergone some form of platform or supplier verification.

Scoring Rationale:
The company demonstrates a credible manufacturing foundation through its factory area and verified supplier status. However, the available staffing scale does not support classification as a large-scale supply chain manufacturer. Based strictly on the provided data, the company fits best as a medium-scale stable factory with basic-to-solid production capacity, rather than a top-tier high-volume industrial supplier.

Final Score: 15 / 20

2. Platform & Compliance Credibility

Basis:
- Gold Supplier: True
- Gold Supplier duration: 13 years
- Trade Assurance: True
- Certification / industry labels: Finished product inspection, Full customization, ODM service available, Minor customization

Elaboration:
The supplier has a long Gold Supplier history of 13 years, which is a strong platform credibility indicator. Trade Assurance support provides additional transactional protection for buyers. The listed platform labels also show coverage across product inspection and customization-related services.

Scoring Rationale:
A 13-year Gold Supplier record, Trade Assurance support, verified supplier status, and multiple platform labels create a strong credibility profile. The compliance and platform information is relatively complete based on the provided data. No external certifications beyond the listed platform labels are provided, so the score is strong but not treated as absolute maximum.

Final Score: 19 / 20

3. Business Performance

Basis:
- Orders in past 6 months: 20+
- Transaction value in past 6 months: CN¥676.1K+
- Store rating: 5.0
- Number of reviews: 6

Elaboration:
The supplier has achieved more than 20 orders and over CN¥676.1K in transaction value during the past six months. This indicates active commercial performance on the platform. The 5.0 store rating is positive, but the review base is limited at only 6 reviews, which reduces the statistical strength of the customer feedback signal.

Scoring Rationale:
The transaction value is meaningful and indicates real buyer activity, while the order count suggests moderate platform traction. However, the order volume is not high enough to classify the supplier as a high-volume performer, and the low number of reviews limits confidence in the rating. Therefore, the supplier fits the stable medium-scale transaction category.

Final Score: 15 / 20

4. Service Capability

Basis:
- Communication response time: ≤6h
- Full Customization: Listed
- ODM service available: Listed
- Minor customization: Listed

Elaboration:
The supplier’s response time of within 6 hours is acceptable for international sourcing communication, though it is not within the strongest ≤1 hour benchmark. The presence of Full Customization, ODM service available, and Minor customization indicates that the supplier can support different levels of customization requests based on the platform labels.

Scoring Rationale:
The customization capability appears stronger than basic service support due to multiple customization-related labels. However, the response time does not reach the highest service tier. Based on the available data, the supplier shows solid service capability but not best-in-class communication speed.

Final Score: 8 / 10

5. Delivery Performance

Basis:
- On-time shipment rate: 91.7%

Elaboration:
The supplier’s reported on-time shipment rate exceeds 90%, which indicates a relatively strong delivery record. This performance level is important for procurement planning, especially for buyers with fixed seasonal, retail, or project-based delivery timelines.

Scoring Rationale:
According to the scoring standard, an on-time shipment rate above 90% falls into the 9–10 point range. At 91.7%, the supplier qualifies for a strong delivery score, although the margin above 90% is not very large.

Final Score: 9 / 10

6. Quality & Customer Feedback

Basis:
- Store rating: 5.0
- Number of reviews: 6
- Finished Product Inspection: Listed
- Verified supplier / factory verification: True

Elaboration:
The supplier has a perfect 5.0 store rating, which is positive, and it also lists Finished Product Inspection as a platform label. Verified supplier status provides additional confidence in supplier legitimacy. However, the review count is only 6, which means the available customer feedback base is relatively small.

Scoring Rationale:
The supplier has good quality-related indicators, including a high rating, finished product inspection, and supplier verification. The main limitation is the small number of reviews, which prevents the quality feedback from being considered highly validated by a large buyer base. The score therefore reflects good but not fully proven quality confidence.

Final Score: 16 / 20

Total Score

82 / 100

• Company Strength: 15 / 20
• Platform & Compliance Credibility: 19 / 20
• Business Performance: 15 / 20
• Service Capability: 8 / 10
• Delivery Performance: 9 / 10
• Quality & Customer Feedback: 16 / 20

Procurement Recommendation

Qingdao Stone Rubber Products Co., Ltd. is recommended as a qualified medium-scale supplier for buyers sourcing wheel-related products, especially where platform credibility, Trade Assurance, customization support, and acceptable delivery reliability are important.

The supplier is most suitable for small-to-medium importers, distributors, e-commerce sellers, and buyers needing customized or ODM-supported wheel products with moderate order volumes. Its 13-year Gold Supplier status, verified supplier profile, Finished Product Inspection label, and 91.7% on-time shipment rate provide a solid sourcing foundation.

Key risks include the relatively limited review count of 6, moderate recent order volume of 20+ orders, and response time of ≤6h, which is acceptable but not premium-level. Buyers should request product samples, confirm inspection standards, clarify customization requirements, and verify production lead times before placing larger orders.

Growth potential is positive if the supplier continues increasing transaction volume, review base, and service responsiveness while maintaining its current delivery and quality indicators.
